Anthropic says its Mythos model found vulnerabilities in cryptographic algorithms that secure the internet

Anthropic's Claude Mythos Preview found weaknesses in key cryptographic algorithms, including a better attack on the post-quantum signature scheme HAWK that human experts had reviewed for more than two years, completing the analysis in 60 hours at an API cost of about $100,000. The findings do not affect systems in use today but show how AI could challenge core assumptions behind internet security, Anthropic said.
